DUST 514 Live Event: Mordu’s Challenge Starts Tomorrow

Since DUST 514 launched as the first free-to-play massively multiplayer first-person shooter on PlayStation 3 in May, the battlefields of New Eden have been exploding with activity. If you haven’t jumped in and created your immortal DUST character yet, our latest in-game event is the perfect time to start your mercenary career.

I already try and take out the turrets, but there usually isn't a ton of people trying to do that. I would guess they'll see that almost no one got that challenge when it's all over and give it to people who got say > 25.
